16. The method according to claim 10 , wherein a time position indicated by the time position information is a time position of the at least one CORESET in one, two or four slots.

17. The method according to claim 10 , wherein the position information of the at least one CORESET in the system frame number comprises: a period of a CORESET burst set being N times of a period of a synchronization signal burst set, wherein N is a positive integer, and the CORESET burst set consists of all CORESETs which complete one round of beam sweeping or consists of all CORESETs specified within a monitoring period of the UE; and an offset between a start time of the CORESET burst set and a start time of the synchronization signal burst set being zero.

18. The method according to claim 10 , wherein the configuration information is received from the base station through Master Information Block (MIB) or Remaining Minimum System Information (RMSI).

19. The method according to claim 17 , further comprising: receiving Demodulation Reference Signal (DMRS) on the at least one CORESET to perform time-frequency tracking.

20. A non-transitory tangible computer readable medium which has computer instructions stored therein, wherein once the computer instructions are executed by a processor, the method according to claim 1 is performed.
